Woolie, I had exactly the same scenario when I bashed the fuse cover with my knee. Do a search for Traffic Master as the earlier poster said and get yourself subscribed, it works brilliantly and can cost as little as a tenner a month for guidance, £20 if you include camera warnings (always up to date), and £30 a month if you include stolen car tracker. When I got in touch I was given a months free trial and was highly impressed. You press your button, get connected by built-in mobile phone link (you might have found a microphone at the top of the door pillar) tell the person who answered the call where you want to go and they download the journey data into the onboard guidance system. Those blue cameras you see at the side of the road are Traffic Master cameras, they enable you to be automatically routed around traffic holdups; the system can save you loads of time on long journeys.
